Up 🎰 Features of playing in non GamStop casinos Getting some playing time despite being signed up on GamStop is something many players appreciate. However, should a player decide to remain active on GamStop and still play every now and again, they can play on gambling sites not on GamStop. It is a completely voluntary process and a player can opt out at any time. This means that they will be prevented from playing on these sites. When a player signs up on, they are automatically placed on a list of players blacklisted on casinos registered on GamStop. It is a platform designed to provide support for UK players who have issues with gambling addiction. Sites not on GamStop may not accept GBP.Players can enjoy high limits (games and withdrawals).
